I have already read the guide on how to use this program in the guides section. But when I try to add any file, I get the msg that

'0 files were successfully added'
'1 File could not be added'
'The.....avi file may be corrupted or not valid'

I am trying to convert an avi(xvid) file to dvd, so I can watch it on my dvd player. But I am unable to do so. The file works fine on my computer, except for Windows media player as I do not have the proper codec installed yet. So, it's not corrupt.

Also, I tried adding various other avi files to convert, but I got the same msg for each. The program isnt allowing me to add any avi files at all. None. I find it highly unlikely that all my movie files are corrupted.


So what am I doing wrong? Any help.....
